Referring first to Figs. 1 to 12 the fountain dispenser for dispensingmixed drinks of syrup and charged water is generally designated at 10.It includes a cooling unit having an outer shell consisting of an outerside wall 11 and a bottom wall 12. which are secured together by screws13 and an angle strip 14. A gasket 15 forms a. support for the coolingunit when it is secured to a fountain bar 148. The upper edge of theside wall 11 is provided with a flanged strip 16 for securing in place asealing gasket 17. The outer shell is filled with suitable insulatingmaterial 18 which operates to insulate a cooling chest formed of asingle unit. The cooling chest includes a side wall 2% and a bottom wallhaving a thick portion 21 and a thin portion 22 with an internalshoulder 1% therebetween. The cooling unit may be supported on thebottom wall 12 of the shell by means of suitable legs 23. A strip 24 andscrews 25 secure the sealing gasket 17 to the cooling chest so that theinsulation 28 is sealed in place between the outer shell and the coolingchest.

The cooling chest is preferably integrally cast from a metal which maybe readily cleaned and which has high heat conductivity such asaluminum. During the casting of the cooling chest a charged water tube27 is integrally cast into the thick portion 21 of the bottom of thecooling chest. Preferably, this charged water cooling tube is made ofstainless steel or the like. The charged water cooling tube is shown indetail in Figs. 8A and 9 and includes a double layer spiral arrangementwherein the two layers communicate with each other by the bent section28 at the interior of the spirals. Charged water is fed into the coolingtube 27 through an extension 29 and is discharged therefrom through anextension 30 and a-fitting 31. The extension 29 is. imbedded in anelongated boss 32 and the extension 30 is imbedded in an measuringchamber elongated boss 33, both of the bosses being formed on the bottomof the cooling chest. The extension 29 projects downwardly from the boss32. The extension 30 bends upwardly through a boss 34 within the coolingchest and the fitting 331 communicates with the exterior of the chestadjacent the bottom of the side wall 26. Thus, the tube 27 provides acontinuous passage in the bottom wall of the cooling chest and in theillustrated embodiment the fitting 31 provides a discharge opening fromthe end of the tube.

In casting the charged water cooling tube in the bot tom wall of thecooling chest the spiral layers are preferably held in place by fourspacer brackets 36 having holes 37 for holding and properly spacing thespiral tube 27. To two of these brackets there is preferably secured arod 33 for properly locating the spiral layers in position during thecasting operation. The wall of the fitting 31 is preferably maintainedthick during casting to prevent collapsing of the fitting which might becaused by shrinkage of the aluminum casting. After the casting iscompleted then the fitting 31 is counterbored to the correct dimension.

The bottom wall of the cooling chest is provided with an upwardlyextending boss 39 adapted to support the syrup container and is alsoprovided with a hole 4%) therethrough in which may be secured a coupling41 for, draining ice water from the cooling chest. When ice is placedwithin the cooling chest it is evident that heat will be rapidlyconducted from the charged Water in the cooling tube 27 thereby coolingthe same. Thus, the end of the extension 29 of the cooling tube 27 andfitting 31 provide one opening in the side wall of the cooling chest andthe side wall adjacent the fitting 31 is provided with an opening 42therethrough adapted to receive a fitting for the purpose of dispensingsyrup.

The shell 11 is provided with a pair of holes 43 and 43, see Figs. 3 and4, and has a plate 44 secured thereto adjacent the fitting 31 and theopening 42. Plate 44 has a pair of openings therein aligned with theholes 43 and 43 and openings in the side wall of the chest and is soshaped as to receive a pair of sleeves 45 and 46 to form communicatingpassages between the cooling chest and shell. The cooling unit may beprovided with a suitable removable cover 48 having a handle 49 toprovide access to the interior of the cooling chest.

A dispensing valve for dispensing syrup and charged Water is secured tothe exterior of the cooling unit adjacent the fitting 31 and opening 42in the cooling chest. This dispensing valve includes a valve housing 50secured by screws 52 to a mounting flange 51. The mounting flange 51 isin turn secured by screws 53 to the plate 44 whereby the valve housingis securely mounted on the cooling unit.

The valve housing is provided with a pair of parallel bores extendinglongitudinally therethrough. One of the bores for the purpose ofdispensing charged water includes a valve bore 55, a valve guide 56 anda valve seat 57 therebetween. The valve bore adjacent the seat 57communicates through a lateral passage 58 with a tortuous passage 59extending downwardly from the valve housing 50 as is illustrated in Fig.5. The tortuous passage is formed by screwing a plug having coarsethreads into a screw threaded opening wherein the threads seat looselyto provide a helical passage. A valve stem 60 is slidably mounted in thevalve guide 56 and carries at its interior end a valve head 62 having avalve member 61 adapted to engage the seat 57. The outer end of thevalve stem is secured to an abutment 63 having a horizontal notch 64. Aspring 65 engaging the abutment 63 operates to hold in place a resilientO-ring 66 about the valve stem 60 for sealing the same against leakage.

A ported member 67 located within the valve bore 55 has an enlargedportion 63 provided with a groove .for receiving a resilient-O-ring 69.The enlarged portion 68 is slidably receivedin the valve bore 55 and theO-ring 69 4 operates to seal the same against leakage. The enlargedportion 68 engages against an abutment 70 in the mount-- ing fiange 51for maintaining the ported member 67 within the valve housing. Theported member extends through the sleeve 45 and into the fitting 31. Theouter end of the ported member 67 is enlarged at 71 and is provided witha groove for receiving an O-ring 72 for 'sealing the ported memberwithin the fitting.

The inner end of the ported member 67 is closed by a wall 73 and isprovided with lateral holes 74. A cup shaped member 75 overlies theinner end of the ported member 67 and is slidable thereover. The innerend of the cup shaped member is provided with a restricted opening 76.The cup shaped member has an internal valving edge for coacting with theholes 74 for regulating the flow of charged water therethrough. A spring77 urges the valve member 61 against its seat 57 and urges the cupshaped member outwardly as is illustrated in Fig. 4.

With the parts in the position shown in Fig. 4 the pressure of thecharged Water on opposite sides of the cup shaped member is equal andthe spring 77 maintains the cup shaped member in the position shown inFig. 4. When, however, the valve stem 61) is depressed to move the valveelement 61 away from the valve seat 67 the pressure on the outside ofthe cup shaped member decreases Whereupon the spring 76 is compressedand the cup shaped member moves inwardly. This movement is provided bythe restricted opening 76 which produces a pressure drop thereacross.The valving edge of the cup shaped member cooperates with the holes 75for controlling the fiow of charged water from the ported member tomaintain a substantially constant pressure drop across the ported end ofthe cup shaped member 75. In this way charged water is regulated tosubstantially constant rate of flow. When the valve stem 60 is releasedand the valve element 61 is moved into engagement with the valve seat57, the pressure drop across the ported end of the cup shaped member 75becomes zero and the spring 77 returns the cup shaped member to theposition illustrated in Fig. 4. Thus, when charged water is dispensedupon opening of the valve, it is dispensed at a substantially constantvelocity.

The other parallel bore in the valve housing 50 includes a valve bore 80and a valve guide 81. The valve bore 80 communicates with a passage 82in which is secured a short tube 83 having a thin plate 84 at its lowerend secured in place by a collar 86. The thin plate 84 is provided withan opening 85 through which syrup is dispensed.

Slidably received in the valve bore 50 is a ported member 88 having avalve seat 89 on its inner end. The ported member 88 is provided with agroove for receiving a resilient O-ring 90 for sealing the ported memberin the valve bore. The ported member is provided with a shoulder 91fitting in a recess in the mounting flange 51 for securing the portedmember within the valve bore. The ported member is provided with anenlargement 92 which is provided with a groove for receiving a resilientO-ring 93 for sealing the same within the sleeve 46. The enlargedportion 92 at its outer end is also provided with an enlarged opening94.

A valve stem 96 is slidably received in the valve guide 81 and carriesat its inner end a valve head 97 having a valve member 98 adapted toengage against the valve seat 89. A spring 99 urges the valve member 98against the valve seat 89. The outer end of the valve stem 96 isprovided with a head 105. The bifurcated end 101 of a lever engagesunderneath the head 105. Intermediate its ends the lever 100 is providedwith a recess 193 by means of which the lever 109 is pivotally mountedon a pin 104 carried by the outer end of the valve housing 50. The otherend of the lever 100 is provided with an extension 102 which is receivedin the horizontal groove 64 of the other valve element.

A handle housing 106 is pivoted by a transverse pin 107 to the outer endof the valve housing 50 and is provided with an operating handle 16%.Located Within the handle housing 106 is a pin which is adapted toengage the extension 1132 of the lever 160. When the handle 108 ispushed inwardly the pin 1119 pushes inwardly against the extension 102of the lever 1%. This causes opening of the charged water valve asheretofore explained. This also causes the lever 101) to pull the valvestem 96 outwardly against the action of the spring 99 so that the valvemember 93 is moved away from the valve seat 39. This permits syrup topass through the valve seat into the tube 83 and hence through theopening 35 in the lower end thereof. When the handle 1% is returned toits original position the charged water valve is closed as heretoforeexplained and the spring 99 moves the valve member 88 against the valveseat 89 to shut off the flow of syrup.

The bottom side of the valve housing 50 is provided with a circularopening for receiving a spout 111. The spout 111 encompasses the syruptube 83 and is held in place by a bayonnet connection 112. A resilientO-ring 113 seals the spout in the opening. When the dispensing valve isopened syrup flows into the center of the spout through the syrup tube83 and charged water flows into the spout through the tortuous passage59. The syrup and charged water are mixed within the spout 111 as thesame is dispensed. Vanes 114 formed in the spout 111 assist in themixing of the syrup and charged Water. Thus, the dispensing valvedispenses a mixture of syrup and charged Water.

Removably located within the cooling chest is a syrup container 121having a float chamber 121 in the bottom thereof. The float chamber isprovided with a depression 122 which communicates with a syrup tube 123having a fitting 124 on its outer end. The fitting 124 is provided witha groove for receiving a resilient O-ring 125 whereby the fitting may beslidably received in and sealed in the enlarged opening 14 in the portedmember 851. The depression 122 of the float chamber 121 is adapted torest on the boss 39 on the bottom wall of the cooling chest so as tosupport the syrup container in the cooling chest with the syrup tube 123in communication with the ported member $8. A spring latch 127 issecured to the bottom of the float chamber 121 and en gages theshould-er 91 on the bottom wall of the cooling chest for the purpose offirmly holding the syrup tube 123 in communicating engagement with theported member 33. A link 128 engages the spring latch 127 and is guidedat its upper end by a bracket 129 secured to the syrup container 120. Ahandle 13%) is located on the upper end of the link 128 so that when thehandle 130 is pulled the spring latch 127 is released to permit removalof the syrup container from the cooling chest. The link 123 alsooperates firmly to latch the spring latch member 127 against theshoulder 119 for holding the syrup container in place. Thus, the syrupcontainer may be readily removed from the cooling chest and may bereadily supported within the cooling chest ina leak proof manner. Thetop of the syrup container 120 may be closed by a suitable cover 132having a handle 133.

A removable wall separates the float chamber 122 from the remainder ofthe syrup container. This removable wall includes a disc 135 coveredwith a resilient material 136 such as rubber. The resilient materialseals the float chamber 121 from the syrup container 120 and therebyprovides a removable partition therebetween. The wall or partition isprovided with a central opening 137 and also with an upwardly extendingvent tube 133.

Located within the float chamber 131 is a float 139 having a valveelement 140 cooperating with the opening 137 for regulating the flow ofsyrup from the syrup container 120 into the'float' chamber 121. Thefloat is guided in the float chamber by means of guide members 141depending from the removable wall or parti-' tion 135.

The valve element 146 of the float 139 when in the upper position asillustrated in Fig. 3 closes the opening 137 to maintain a predeterminedlevel of syrup Within the float chamber. When the dispensing valve isopened to dispense syrup and charged Water, syrup is withdrawn from thefloat chamber. When this occurs the float 13$ moves downwardly to permitadditional syrup to enter the float chamber from the syrup container andthis will continue until the level of the syrup in the float chamber 121is restored to the original value. Thus, the float 139 operates tomaintain a substantially constant head or level of syrup within thefloat chamber. In this way when syrup is dispensed through the.dispensing valve it is dispensed at substantially a constant velocitysince the head of the syrup remains substantially constant. Hence inaccordance with this form of the invention both the syrup and thecharged Water are dispensed at constant velocity during the dispensingoperation so that a predetermined mixture of syrup and charged water isassured regardless of the size of the mixed drink dispensed. The venttube 138 maintains atmospheric pressure above the syrup in the floatchamber 121.

A clamping bracket is secured to the bottom wall 12 of the cooling unitby means of screws 146. The clamping bracket 145 carries a screw clamp147 for the purpose of securely mounting the cooling unit on a fountainbar 148 with a portion of the cooling unit overhanging the fountain bar.The gasket 15 seals the cooling unit to the fountain bar. A dependingskirt 151} is suitably secured to the overhanging portion of the outershell of the cooling unit and it is internally provided with a pair ofguide brackets 151. A hanger 152 is received within the skirt and isprovided with flanges 153 engaging the guide brackets 151 so that it maybe vertically adjusted with respect to the skirt. The hanger is providedwith a vertical slot 154 for receiving a screw and nut assembly 155adjustably to position the hanger vertically with respect to the skirt.The hanger carries a hollow tray 156 provided with a reinforcing flange157 and a spout 158. Any liquid which is spilled into the tray 156 isconveyed therefrom by the spout 158. A suitable disposal tube,

not shown, may be secured to the spout 158.

The skirt 150 also carries a charged water shut off valve having ahousing 169. The valve housing 160 is provided with an internal bore 161and a shoulder 162. The valve housing also includes a valve seat 163 anda threaded extension 164, which extension is provided with longitudinalinternal grooves 165. The threaded extension 164 is adapted to becoupled by a suitable coupling 167 to a charged water supply line 166.The side wall of the valve housing 160 is provided with a screw threadedopening 168 for receiving a nipple 169 to which is secured the coolingtube extension 2@ by means of a fitting 170.

Within the bore 161 of the valve housing 160 there is slidably receiveda member 171 having a groove 172 for receiving a resilient O-ring 173which operates to seal the member 171 in the valve housing 160. Themember 171 is provided with a central valve guide 174. it is alsoprovided with an internal shoulder 175 for the purpose of supporting acylindrical screen 176 between it and the shoulder 162. Thus, chargedwater passing through the shut off valve must pass through thecylindrical screen 176.

Slidably mounted Within the screw threaded extension 164 is a valve head1% carrying a valve member 181 adapted to engage the valve seat 163. Aspring 182 located between the valve head and a ported partition 133secured in the threaded extension urges the valve member 181 against theseat 163. A valve stem 184 is slidably and rotatably received in thevalve guide 174 and it is provided with a groove for receiving aresilient O-ring 185 for sealing the same. A spring ring 186 preventsremoval of the valve stem. The inner end of the valve stem 184 engagesthe valve head 18% and when the valve stem is pushed inwardly the valvemember 181 is moved away from the valve seat 163 against the action ofthe spring 182. Charged water passes around the valve head 180 throughthe longitudinal grooves 165 and then past the valve seat and throughthe screen 176. When the valve stem 184 is released the spring 182 movesthe valve member 181 against the valve seat 163 to shut off the flow ofcharged water. The outer end of the valve stem 184 is provided with ahandle 187 for manipulating the valve stem.

The valve housing 160 is secured to the skirt 150 by means of a pair ofscrews 196. A generally U-shaped plate 191 is secured in place by thesame screws 190, one screw 190 passing through a hole in the plate 191and the other screw 190 passing through a slot in the plate 191. Theplate 191 engages in a groove 193 in the member 171 for locking themember in position. The plate 191 is also provided with a hook 194 underwhich the handle 187 may be hooked. To open the shut off valve the valvestem 184 is pushed inwardly and the handle rotated underneath the hook194 whereby the valve stem 184 is held inwardly. To close the shut offvalve the handle 187 is rotated from underneath the hook 194 and thenthe valve stem 184 is pushed outwardly by the spring 182. In order todisassemble the valve for cleaning purposes, the plate 191 is rotatedout of the position shown in Fig. 11. This being permitted by the slot192. The plate 191 is thus moved out of engagement with the groove 193in the member 171 whereby the member 171, the valve stem 184 and thescreen 176 may be removed from the valve housing. The form of theinvention illustrated in Figs. 13 to 19 is substantially the same as theform of the invention illustrated in Figs. 1 to 12 and like referencecharacters have been utilized for like parts. This form of the inventiondiffers from the form of the invention previously described in twoessential respects. One is in the manner of dispensing the syrup and theother is in the manner of mounting the cooling unit on the fountain bar.

Considering first the first difference, the syrup container isdesignated at 200 and is provided with a suitable cover 201. The bottomof the syrup container has an auxiliary chamber 202 in which is securedan extension 203, the upper edge of the extension 203 forming a seat204. The extension 203 communicates with a syrup tube 205 provided atits end with a fitting 266 carrying a resilient O-ring 207. The fitting206 is slidably received in the enlarged opening 94 of the ported member42 so that the syrup tube may be removably received therein. Theextension 203 rests upon the boss 39 for supporting the syrup container.A spring latch 210 is secured to the bottom of the syrup container 260and engages the shoulder 19 of the cooling chest for securing the samein place. Here again the spring latch member 210 is manipulated by alink 211 and handle 213 guided by a bracket 212.

Movably located within the auxiliary chamber 202 is a measuring chamber215 having a cover 216. The cover is secured in place by spring arms 217and pins 213. The cover is provided with a vent tube 219 extendingupwardly therefrom. The measuring chamber 215 is provided with aninternal seat 220. The bottom of the measuring chamber 215 is providedwith a plate 221 for engaging the seat 204 formed by the upper edge ofthe extension 203. The plate 221 is provided with a central opening 222.The bottom of the plate 221 is provided with lateral projections 223 inthe form of a spider for carrying a sleeve 224 having openings 225therein. The lateral projections 223 operate to guide the measuring 8chamber 215 with respect to the extension 203. Located within themeasuring chamber 215 is a float 226 which in its downward positionengages the seat 220 to seal oif the central opening 222 and which inits upper position engages stops 227 carried by the cover 216 of themeasuring chamber.

A rod 230 extends inwardly through the syrup tube 205 and is adapted toengage the lower end of the sleeve 224 to tilt it to the position shownin Fig. 16 or to allow it to become vertically positioned as illustratedin Fig. 17. The outer end of the rod 230 is secured to the valve stem 96by a pin 231. A valve head 232 is slidably mounted on the rod 230 andcarries a valve member 233 adapted to engage the seat 89 of the portedmember. A spring 234 urges the valve member 233 against the seat 89 anda spring 235 urges the valve stem 96 inwardly. A resilient O-ring 237 islocated between the valve head 232 and the valve stem 96 to limit theinward movement of the valve stem 96. The rod 230 is provided with ashoulder 238 adapted to engage the valve head 232 for moving the valvemember 233 away from the valve seat 89 against the action of the spring234.

When the dispensing valve is closed, as illustrated in Figs. 16 and 19,the rod 230 maintains the measuring chamber 215 in the tilted position,syrup fills the syrup tube 205 and the extension 203 and also entersthrough the central opening 222 to fill the measuring chamber 215whereupon the float 226 is in the raised position as illustratcd in Fig.16. When the dispensing valve is opened the valve stem 96 is movedoutwardly to pull the rod 230. When this occurs the measuring chamber215 moves to the vertical position as illustrated in Fig. 17 and theplate 221 seals against the valve seat 204 to prevent syrup from beingdischarged from the syrup container 200. When the rod 230 is retractedthe shoulder 238 engages the valve head 232 to move the valve member 233away from the seat 89 so that syrup may be dispsensed. When this occurssyrup flows from the measuring chamber 215 through the central opening222 until the float 226 engages the seat 220. When this occurs the flowof syrup is stopped even though the valve member 233 is away from thevalve seat 89. Thus, a measured quantity of syrup determined by thesyrup contained in the measuring chamber 215 is dispensed. When thedispensing valve is closed the valve member 233 engages the valve seat89 to prevent further discharge of syrup and the rod 230 tilts themeasuring chamber 215 to the position illustrated in Fig. 16 wherebysyrup enters through the central opening 222 to refill the measuringchamber 215. Refilling and emptying of the measuring chamber 215 ispermitted by means of the vent tube 219. Thus, in accordance with thisform of the invention when the dispensing valve is opened a measuredquantity of syrup is dispensed.

The cooling unit of the form of the invention illustrated in Figs. 13 to19 is illustrated to be mounted on the syrup rail of a fountain bar. Inthis connection the outer shell of the cooling unit has secured theretoa bottom plate 242 which supports through spacers 240 and screws 241 thebottom wall 12. A sealing gasket 239 seals the bottom wall 12 to thecooling unit. The bottom plate 242 carries a depending skirt 243 havinga pair of downwardly extending parallel extensions 244. A pair of clips245 secured to the bottom plate 242 receive tongues 246 carried by theskirt 243 for the purpose of securing the cooling unit to the skirt. Abracket 24-7 is also secured to the skirt 243 and a cooperating bracket250 is secured to the bottom plate 242. A screw 248 and a out 249 clampthe two brackets together. ing unit on the skirt the cooling unit isslid forwardly with respect to the skirt to cause the clamps 245 toengage the tongues 246 and to cause the bracket 250 to engage thebracket 247. The screw 24 8 and nut 249 secureiy hold the cooling uniton the skirt. Thus, the cooling unit is detachably carried by the skirt.

Iii-mounting the cool- On each extension 244 there is secured a bracket252 each having an elongated slot 253 for the purpose of adjustablymounting a U-shaped clamp member 254.
